| colliculus facialis | Prominent portion of the medial eminence, just rostral to the medullary striae in the rhomboidal fossa; it is formed by the internal genu of the facial nerve and the abducens nucleus around which the facial fibres curve. Synonym: colliculus facialis, abducens eminence, eminentia abducentis, eminentia facialis, facial eminence, facial hillock. (05 Mar 2000) |
|---|---|
| colliculus inferior | The ovoid, paired, inferior eminence of the laminae of mesencephalic tectum; it receives the lateral lemniscus and projects by way of the brachium of inferior colliculus to the medial geniculate body of the thalamus, and is thus an essential way-station in the central auditory pathway. Synonym: colliculus inferior, corpus quadrigeminum posterius, inferior nasal colliculus, posterior quadrigeminal body. (05 Mar 2000) |
| colliculus of arytenoid cartilage | The elevation on the anterolateral surface of the arytenoid cartilage above the triangular fovea. Synonym: colliculus cartilaginis arytenoideae. (05 Mar 2000) |
| colliculus seminalis | An elevated portion of the urethral crest upon which open the two ejaculatory ducts and the prostatic utricle. Synonym: colliculus seminalis, caput gallinaginis, colliculus urethralis, seminal hillock, verumontanum. (05 Mar 2000) |
| colliculus urethralis | An elevated portion of the urethral crest upon which open the two ejaculatory ducts and the prostatic utricle. Synonym: colliculus seminalis, caput gallinaginis, colliculus urethralis, seminal hillock, verumontanum. (05 Mar 2000) |
| seminal colliculus | An elevated portion of the urethral crest upon which open the two ejaculatory ducts and the prostatic utricle. Synonym: colliculus seminalis, caput gallinaginis, colliculus urethralis, seminal hillock, verumontanum. (05 Mar 2000) |
| nucleus of inferior colliculus | The nerve cell groups composing the colliculus inferior. Synonym: nucleus colliculi inferioris. (05 Mar 2000) |
| inferior colliculus | The ovoid, paired, inferior eminence of the laminae of mesencephalic tectum; it receives the lateral lemniscus and projects by way of the brachium of inferior colliculus to the medial geniculate body of the thalamus, and is thus an essential way-station in the central auditory pathway. Synonym: colliculus inferior, corpus quadrigeminum posterius, inferior nasal colliculus, posterior quadrigeminal body. (05 Mar 2000) |
| inferior nasal colliculus | The ovoid, paired, inferior eminence of the laminae of mesencephalic tectum; it receives the lateral lemniscus and projects by way of the brachium of inferior colliculus to the medial geniculate body of the thalamus, and is thus an essential way-station in the central auditory pathway.

| facial colliculus | Prominent portion of the medial eminence, just rostral to the medullary striae in the rhomboidal fossa; it is formed by the internal genu of the facial nerve and the abducens nucleus around which the facial fibres curve. Synonym: colliculus facialis, abducens eminence, eminentia abducentis, eminentia facialis, facial eminence, facial hillock. (05 Mar 2000) |
| anterior gray column | The central gray matter of the spinal cord surrounding the central canal. Synonym: substantia intermedia centralis et lateralis, anterior gray column, Stilling's gelatinous substance, substantia gelatinosa centralis. (05 Mar 2000) |
| matter, gray | The cortex of the brain which contains nerve cell bodies. The gray matter is as opposed to the white matter, the part of the brain that contains myelinated nerve fibres. The gray matter is so named because it in fact appears gray. In the mysterious affair at styles (1920), agatha christie first quoted the fictional belgian detective hercule poirot in regard to his gray matter: 'this affair must be unravelled from within.' he tapped his forehead. 'these little grey cells. It is up to them as you say over here.' (12 Dec 1998) |
| central gray substance | In general: the predominantly small-celled gray matter adjoining or surrounding the central canal of the spinal cord and the third and fourth ventricles of the brainstem, in particular: the thick sleeve of gray matter surrounding the cerebral sylvian aqueduct in the midbrain, rostrally continuous with the posterior nucleus of the hypothalamus; in sections stained for myelin it stands out from the adjoining tectum and tegmentum by the poverty of its myelinated fibres. Synonym: substantia grisea centralis. (05 Mar 2000) |
| periaqueductal gray | Central gray matter surrounding the cerebral aqueduct in the mesencephalon. Physiologically it is probably involved in rage reactions, the lordosis reflex, feeding responses, bladder tonus, and pain. (12 Dec 1998) |
| Gray | <radiobiology, unit> The new international system unit (SI unit) of absorbed dose of radiation (Gy), 1 Gy = 1 J kg-1 = 100 rad. (16 Dec 1997) |
